Abstract

The invention provides a high-level rainwater flower bed for sponge city rainwater storage and purification. The high-level rainwater flower bed is arranged on one side of a building external wall and comprises a vegetation region, a flower bed base layer, a flower bed compacting soil layer and an overflow pipe. The flower bed base layer comprises a vegetation cultivation layer, a middle rubble layer and a water storage layer which are laid from top to bottom, the vegetation cultivation layer and the middle rubble layer are isolated by a permeable geotextile, and the overflow pipe penetrates the vegetation region and the flower bed base layer and is vertically communicated with an upper drainage pipeline and a bottom drainage pipeline, parallel to the outer wall of the flower bed and perpendicular to the ground. The rainwater flower bed is standard and practical, can effectively realize rainwater resource utilization and has the advantages of water-saving, energy-saving and land-saving properties and the like required by contemporary green buildings.

Description

technical field [0001] The invention relates to the field of drainage engineering based on the concept of a sponge city, in particular to a high-level rainwater flower bed used for storing and purifying rainwater in a sponge city. Background technique [0002] my country's water resources are rich in overall and the per capita possession is small. In many areas, water shortages or water quality shortages exist. Rainwater carries a large amount of surface pollutants in the process of falling and collecting, seriously polluting rivers. At the same time, rainwater is a non-traditional water resource. Rainwater infiltration can conserve groundwater sources, and rainwater reuse can make up for the shortage of some water resources and reduce non-point source pollution of rivers. [0003] Since the release of the "Technical Guidelines for Sponge City Construction", there has been an upsurge in the construction of sponge cities in China. The ultimate goal of sponge city construct...
